Filing your Minnesota tax return for 2021 is important in meeting your state and federal tax return obligations. Knowing the tax filing procedure can help you avoid delays and receive your refund more quickly, regardless of whether you are an individual taxpayer, small business owner, or this is your first time filing. The forms you require, the payment and refund procedure, and the choices you have to properly prepare and submit your return will all be covered in this guide.

Assess your residency status, income, and other circumstances to see if you must file before you begin. The process will go more smoothly if you gather all required paperwork, including prior year income tax returns, W-2s from your employer, deduction receipts, and any pertinent federal tax information. Having this data ready ensures you can complete your return without missing important details that might affect your eligibility for deductions or credits.

Minnesota provides a number of filing options, such as e-file services, free file programs for eligible individuals, hiring a tax preparer, or using software from authorized businesses. By selecting the appropriate approach, you can minimize inconvenience, preserve accuracy, and get the most out of your refund. Whether you decide to prepare your taxes or seek expert help, this guide will provide clear guidance from start to finish.

Determine If You Need to File a Minnesota Tax Return

Before starting the tax filing process, it is important to confirm whether you are required to submit a return for the 2021 tax year. Filing requirements depend on your income level, residency status, and type of income earned.

1. Review income thresholds

If your income in 2021 was above the minimum required by the state, you must file a Minnesota tax return. Thresholds vary depending on filing status, age, and whether you are claimed as a dependent. Even if your income is below the threshold, filing may benefit you if you qualify for a refund or certain tax credits.

2. Determine your residency status

  • Resident: You lived in Minnesota for the entire year. All income, including wages, self-employment earnings, and income from other states, must be reported.

  • Part-year resident: You lived in Minnesota for part of the year and must report all income earned while a resident, plus income from Minnesota sources when you were not a resident.

  • Nonresident: You lived outside Minnesota for a year but must report income earned from Minnesota sources.

3. Consider your employment and income sources

You may also have to file a state return if you received wages from an employer, self-employment income, or payments requiring reporting on a federal tax return. This includes freelance income, business earnings, and taxable benefits.

4. Filing requirements for small businesses

Owners of small businesses, including sole proprietorships and partnerships, must file if their business generated taxable income in Minnesota. You may also need to submit additional forms for specific business taxes, such as sales tax or withholding tax.

5. Special circumstances

You may be required to file even if your income is below the usual thresholds. Examples include:

  • You owe state taxes from a prior year.

  • You received certain taxable payments, such as unemployment benefits.

  • You need to claim a refund for taxes withheld by your employer.

Determining whether you must file will help you avoid penalties, claim any refund owed, and comply with Minnesota and federal taxes. If unsure, a tax preparer or approved e-file program can help you verify your filing requirements.

Determining Your Filing Status

Your filing status is important to the Minnesota tax return process because it determines your tax rates, deductions, and eligibility for certain credits. Choosing the correct status helps you complete your forms accurately and avoid issues with the IRS or the state.

Common filing statuses

  • Single: You are unmarried, legally separated, or divorced as of December 31, 2021.

  • Married filing jointly: You and your spouse combine your income and deductions on one return.

  • Married filing separately: You and your spouse file separate tax returns, which can affect deductions and credits.

  • Head of household: You are unmarried and paid more than half the cost of keeping up a home for a qualifying person.

  • Qualifying widow(er): You meet specific IRS and state requirements and can use this status up to two years after your spouse’s death.

Why filing status matters

Your filing status affects the amount of taxes you owe, your refund potential, and whether you qualify for certain deductions or credits. If you are unsure which status applies, a tax preparer, e-file program, or free file service can help you determine the correct choice. Using the right status ensures accuracy and helps you avoid delays in processing your return.

Gather the Necessary Forms and Documents

Preparing your Minnesota tax return begins with collecting the right paperwork. Having everything ready before you start the tax preparation process will make it easier to complete your forms accurately and avoid delays.

Income-related documents

  • W-2 forms from each employer showing wages earned and taxes withheld.

  • 1099 forms for freelance work, contract income, interest, dividends, or other taxable payments.

  • K-1 forms if you received income from a partnership, S corporation, or trust.

  • Records of unemployment benefits or other taxable assistance.

Minnesota-specific forms

  • Form M1 is the main state income tax return for residents.

  • Form M1PR is used to claim a property tax or renter’s refund.

  • Form M1NR is for nonresidents or part-year residents reporting Minnesota income.

  • Form M1W is used to report Minnesota income tax withheld.

Deduction and credit documentation

  • Receipts for deductible expenses such as charitable donations, mortgage interest, or qualifying medical expenses.

  • Proof of education-related expenses if you are claiming an education credit.

  • Records for child and dependent care expenses.

Proof of payments and prior returns

  • Documentation of estimated tax payments made during 2021.

  • Copies of prior income tax returns for reference.

  • Confirmation of any balance still owed from previous years.

Personal identification and other data

  • Social Security numbers or Individual Taxpayer Identification Numbers (ITINs) for all individuals listed on the return.

  • Your current address and phone number.

  • Bank account and routing numbers for direct deposit of your refund.

These documents will help you complete your Minnesota tax return efficiently, whether you e-file, use a free file program, or work with a tax preparer. Organizing your data in advance improves accuracy and reduces the chance of errors that could delay your refund.

Choose Your Filing Method

Minnesota offers several options for submitting your tax return, allowing you to choose the method that works best for your needs, budget, and comfort level with technology.

E-filing options

  • Use an approved e-file provider listed on the Minnesota Department of Revenue website.

  • Take advantage of free file programs if you qualify based on income or other eligibility criteria.

  • E-filing offers faster processing, built-in accuracy checks, and confirmation that your return was received.

Paper filing

  • Download and print forms from the Minnesota Department of Revenue website or request them by mail.

  • Mail your completed forms to the correct address listed in the official instructions.

  • Allow extra time for delivery and processing, as paper returns take longer to complete and verify.

If you cannot file on your own, you can work with a tax preparer or use software from approved companies to complete your return. Some taxpayers prefer this approach for its expert help, convenience, and guidance.

Step-by-Step: Completing Your Minnesota Tax Return

Completing your Minnesota tax return is easier when you follow a structured process. Taking it step-by-step will help you stay organized, avoid mistakes, and ensure your income tax returns are filed correctly with the state and the IRS.

Step 1: Start with your federal return

Complete your federal tax return first. Minnesota uses information from your federal return, such as adjusted gross income, deductions, and credits, to determine your state tax liability. Completing your federal taxes ensures you can transfer accurate data to your state forms without having to recalculate figures.

Step 2: Fill out Form M1

Form M1 is the main Minnesota income tax return for residents. Enter your personal information, including your name, address, Social Security number, or Individual Taxpayer Identification Number (ITIN). Include your filing status, which determines your tax rate and available deductions. Report all sources of income, whether from your employer, self-employment, or investments, and ensure figures match your federal return.

Step 3: Complete additional forms and schedules

Depending on your situation, you may need extra forms:

  • Form M1PR to claim a property tax refund or renter’s refund.

  • Form M1NR if you are a part-year resident or nonresident.

  • Form M1W for reporting Minnesota income tax withheld from your wages.
    Attach any relevant schedules for deductions, credits, or other adjustments.

Step 4: Enter deductions and credits

Review the deductions and credits you qualify for, such as education credits, child and dependent care credits, or charitable contribution deductions. Gather receipts and documentation to support each claim. This step can reduce the amount you owe or increase your refund, helping you get the maximum refund possible.

Step 5: Verify all information for accuracy

Double-check your entries for accuracy, especially Social Security numbers, income amounts, and bank account details for direct deposit. Mistakes can delay your refund or require identity verification from the state. Confirm that all forms are complete and signed before filing.

Step 6: Sign and date your return

Whether you e-file or mail your forms, you must sign and date your return to make it valid. Unsigned returns will not be processed, which can cause significant delays in issuing your refund or applying your payment.

Step 7: Keep copies for your records

Store a copy of your completed tax return, receipts, and supporting documents in a safe place. Keeping records for several years helps if you are unable to locate details later or need to amend a prior year’s return. It also ensures you have access to the data in case of an audit.

Following this process from start to finish helps you prepare your own taxes with confidence, avoid common filing errors, and meet both state and federal deadlines without unnecessary hassle.

How to Make a Payment

If you owe taxes when filing your Minnesota return, you have several payment options.

Payment methods

  • Direct bank transfer (ACH) is secure and free to use.

  • Credit or debit card payments may include a processing cost charged by a third-party provider.

  • Check or money order made payable to the Minnesota Department of Revenue, sent to the address listed in the payment instructions.

Deadlines and penalties

Taxes owed for the 2021 filing year must be paid by April 18, 2022, even if you request an extension to file your return. Late payments can result in penalties and interest, which increase the total amount you owe.

Paying your balance in full and on time will help you avoid extra charges, maintain compliance with state and federal taxes, and keep your account in good standing. Contact the Minnesota Department of Revenue to discuss payment plan options if you cannot pay the full amount.

Requesting an Extension

If you need more time to complete your Minnesota tax return for 2021, you may be eligible for an automatic extension.

  • Minnesota follows federal tax return extension rules. If you request a federal extension by the April 18, 2022, deadline, you automatically receive a Minnesota extension until October 15, 2022.

  • Even with an extension to file, you must pay any taxes owed by April 18, 2022, to avoid penalties and interest.

  • To ensure your payment is processed on time, use the state’s e-file system or a free file program, or mail it with the appropriate form.

An extension gives you extra time to prepare your return and gather documents, but does not delay the payment due date.

Claiming Your Refund

If you are owed a refund after filing your Minnesota tax return, you can receive it by direct deposit or paper check.

  • Direct deposit is the fastest option and avoids delays from mailing.

  • You can check the status of your refund on the Minnesota Department of Revenue website, “Where’s My Refund?” by providing your Social Security number, refund amount, and tax year.

  • Refunds may be delayed if your return requires additional review, if there are errors, or if identity verification is needed.

Tracking your refund online allows you to estimate when you will receive your money and confirm that your return was processed.
